Robust Maximum Torque per Ampere (MTPA) Control of PM- Assisted SynRM for Traction Applications

This paper presents a control method for permanent magnet assisted (PMa) synchronous reluctance motors (SynRM). These motors are increasing in interest for applications in hybrid electric vehicles (HEV). Utilizing online parameter variation estimation, the control is an attempt to determine the maximum torque per ampere (MTPA) in engine cavities that often have a high level of variability so effective motor parameters. In order to optimize single operating points electromagnetic torque is increased. As this optimization is sensitive to the motor parameters that fluctuate given other variables, the MTPA is used to estimate these variables and so facilitate optimization. Using an online procedure for the estimator ensures robustness against the variation of the load. Experimental and simulation results are provided.
